Abstract

The suction performance of turbopumps in cryogenic fluids is basically much better than that in cold water because of thermodynamic effect of cavitation. However, it is not still clear how the thermodynamic effect works on cavitation instabilities such as rotating cavitation and cavitation surge. In the present study, the singularity method is combined with an unsteady heat transfer model to examine the thirmodynamic effects on rotating cavitation. The results are qualitatively compared with existing experiments to clarify the research needs for deeper understanding.
